Before describing the detailed arrangement of the parts of the machine,a general description will be given of the various units and theirlocation in the machine. The machine embodies a card feed and cardhandling section. which is shown in the upper right hand corner in Fig.1a, and also shown in cross-section in Fig. 2. This part of the machineis arranged to feed cards and derive readings therefrom and afterwardspass the cards into a punching section of the machine which is a punchof the successive column punching type. In the present application onlya fragment of this punching structure is shown as its details form nopart of the present invention.

The counters and receiving devices of the machine are as follows. In theupper part of the machine there are shown an RH accumulator generallydesignated RH on Fig. 1a and an LH accumulator generally designated LHon Fig. 1. Also shown in the upper part of the machine there is asummary products accumulator designated SP. In the lower part of themachine there are two counters which are used as multiplier andmultiplicand entry receiving devices. Such counters or receiving devicesare respectively designated MP and MC on Fig. 1. In the lower part ofthe machine there is also an IVC counter generally designated IVC onFig. 1.

The machine also includes a multiplying panel relay unit which is in thelower part of the machine, the same being generally designated MFR.

In the lower part of the machine there is also provided a column shiftunit generally designated CS. In the present embodiment the column shiftunit is of the multi-point mechanically controlled relay type. Themachine also includes a number of emitter mechanisms and cam contactdevices.

Machine drive The machine is adapted to be driven by a constantlyrunning motor M (Fig. 1a) This motor through a belt and pulley drive andratchet drive 45, drives a shaft 5| (Fig. 1), which shaft drives an A.C. D. C. generator 52. The A. 0. end of this generator is adapted toproduce the impulses for actuating the various counter magnets andcertain of the relay magnets in the machine and this generator 52 has aD. C. (direct current) takeoff section. In short, the generator 52 isprovided with both slip rings for taking off the A. C. impulses andcommutators and brushes for taking off direct current.

Shaft 5| also through the worm gear drive 53 drives a vertical shaft 54which shaft drives the units in the upper section of the machine and theunits in the lower section of the machine. The drive to the units in theupper section will be first described.

Shaft 54 at its upper end through worm gearing 55 is adapted to drivethe counter drive shaft 56 of the machine. The various counters aredriven from this counter drive shaft in the customary manner. The drivefor reset of the counter units is effected in the followingmanner. Shaft56 is provided with a spur gear 51 driving a gear 58 with afour to onedrive ratio. Gear 58 has extending from it four Geneva pins 59cooperating with the other or cross element of the Geneva designated 60.Secured to element 50 is an internal gear 6| which gear has cooperatingwith it a spur gear 62 mounted on the end of the reset shaft 53. TheGeneva cross element 60 also has a shaft 64 which extends to anotherinternal gear 61a similar to gear 5| and having cooperating with it aspur gear 62a similar to gear 62 which drives the reset shaft 630 forthe RH accumulator unit in the upper right hand part of the machine (seeFig. 1a). The drive for the lower units of the machine is substantiallythe same as previously described, that is the shaft 54 through the wormgearing 55b drives the lower counter drive shaft 5617. A similar Genevadrive 51b, 58b, 59b and 60b is adapted to drive an internal gear Slbwhich in turn drives a pinion 62b mounted on the end of the lower resetshaft 53b. The lower reset shaft 631) resets the MP and MC receivingdevices and IVC counter in the customary manner. The lower drive shaft56b also extends to the right and drives an operating cam 55, which camis adapted through a follower 66 to actuate a cross sleeve 6.! andoperate certain shifting mechanism for the multiplier panel relay unitcontact assemblages. A similar cam 65b is also provided driven fromshaft 56b, which cam through a follower 55b is adapted to actuate across sleeve 61a and operate the shifting mechanism for the column shiftrelay units of the machine.

Card feed and card handling unit drive Referring to Fig. 1a the shaft 56at its extreme right hand end is provided with a gear 68 which throughan idler gear 69 drives a gear 10, which through its shaft drives gear"II, which gear 'H in turn drives a gear 12. Gear 12 in turn drives agear 13, revolvably mounted on shaft 15. Gear 13 has fixed to it oneelement 16 of a one revolution clutch, the complemental part of whichcomprises a pawl 11 carried by an arm 18 which is fixed to shaft 15. Theone revolution clutch is the customary type used in tabulating machinesand this one revolution clutch is engaged by the energization of theusual clutch magnet. with the one revolution clutch engaged, it will beunderstood that the shaft 15 will rotate in unison with gear I! and withthe one revolution clutch disengaged 13 will continue its rotation andshaft 15 will remain stationary. Gear 13 also drives an intermediategear 15 which in turn is fixed to a gear 80, which gear 8!! drives atrain of gears 8|, which in turn drive the card feed rolls 52 of themachine. The feed rolls 5! are constantly rotating feed rolls, the samerotating at all times when gear 13 is rotating and at all times when themain counter drive shaft 56 is rotating. Also in train with gear 19 is agear '3 which gear constantly drives a. drag roll shaft .4 having fixedthereto a pair of drag rolls 85.

It will be understood from the foregoing that the card feed rolls 82 andthe drag ro11s.85 constantly rotate at all times during the operation ofthe machine when the driving motor is in operation.

The drive of the parts from the intermittent element of the onerevolution clutch will now be described.

The shaft 15 has secured to it a gear 88 and also secured to the shaft15 is a card transfer and contact cylinder 81. As shown, the onerevolution clutch element 16 is provided with two notches and thearrangement of this clutch is such that whenever the pawl 11 is engaged,the element 18 of the one revolution clutch will make one completerotation. The one revolution clutch pawl 11 may be engaged in either ofthe two notches of the clutch element 18 which relation of the clutchmembers is provided because one counter cycle is required to traversethe card and carry it past the sensing brushes and another counter cycleis required to deliver the card to the punching section of the machineand since it is desired that the clutch be engageable with out delayupon the counter drive shaft turning through either an odd or evennumber of revolutions.

Drive to intermittently actuated contacts Gear 86 previously mentionedas being fixed to the shaft 15 drives a gear 98, which gear in turndrives an idler gear 9|, driving a gear 92 fixed to earn contact driveshaft 93. Shaft 98 has secured upon it a number of cams for actuatingcontact devices which are generally known as the FC group of camcontacts of the machine. The arrangement of these cams is such that theymake one revolution per card feed cycle in contradistinction to acounter-cycle. Fixed to the shaft of gear 98 are card feed rolls 98,which rolls are spring pressed into contact with the card transfer andcard contact cylinder 81. Similar spring pressed card feed rolls 95 alsocooperate with the transfer contact cylinder 81 and these rolls aredriven by a gear 98 in train with gear 88.

It may be here mentioned that the feed rolls 98 and 95 are preferablymade of insulating material inasmuch as they at times contact with thetrans-- ferring contact cylinder 81 which receives current.

\ Card picker drive Shaft 15 on one end has secured to it a box cam 91,which box cam has a follower 98 cooperating therewith. The cam followerconnects to a rock shaft I82, which rock shaft carries gear sectors I83.Gear sectors I82 are in engagement with the picker blocks I84 (see Fig.2). By the engagement of the one revolution clutch the picker is calledinto action and the advance of the picker withdraws a single card fromthe magazine I85 (Fig. 2) and advances this card into the bite of therolls 82. The rolls 82 in turn forward the card to the card transferroll 81. A curved card guide is provided around the transfer cylinderand the advancing card is carried around by the forward rotation of thetransfer cylinder and by the rotation of rolls 9! so as to be traversedunder the main card sensing brushes generally designated I89 in Fig. 2.Also in cooperation with the card is a pivoted card lever III, whichlever III has a tail portion arranged to bear against the upper surfaceof the card. With the card in position under this tail of the cardlever, contacts II2 will be closed. I

- identical.

After the card has been sensed by the main sensing brushes I89, it isadvanced by the cooperation of feed rolls with the transfer cylinder 81between guiding members Ill and H5. While between these guiding membersthe card is advanced by the cooperation therewith of the drag rolls .85,such rolls extending downwardly into recesses of .he lower members H8 inthe manner shown in Fig. la. This arrangement of drag rolls and recessesprovides for a gripping of the card and an advance of the card after ithas been released by the rolls 95 so that the card may be delivered intothe tray of the punching section of the machine. The drag rolls 85 (Fig.2) deliver the card under a guide member II1 (Fig. 2) and after the cardhas been freed from the drag rolls the card is flipped down into thetray of the punching section of the machine. The location of the tray isgenerally indicated at H8 in Fig. 2 and the position of the card in thistray is indicated at R in Fig. la. A card lever II9 (Fig. 2) is alsoprovided adjacent the tray portion Ill and this card lever is arrangedto close card lever contacts I28 when a card is lodged in the tray ofthe punching section of the machine.

The foregoing description has described the manner in which a card iswithdrawn from the supply magazine I85 and the manner in which the cardis carried past the main sensing brushes I89 and the manner in which thecard is delivered into the punching section of the machine. With thetraverse of the card past the sensing brushes the amount of themultiplier and multiplicand and extra amount will have been read fromthe card and entered into the'MP receiving device and into the MCreceiving device and into the IVC receiving device.

The MP receiving device, the MC receiving device and the LH and RHaccumulators, the IVC counter and the SP counter are of the usual typeas customarily used in tabulating machines and are provided forelectromagnetically actuated clutches. The various accumulators andreceiving devices have commutator type readout devices which will behereinafter more fully described.

Multiplying panel and column shift relays one relay will suflice forboth as the action is I These multi-contact relays which are used forcolumn shift and multiplier control purposes will now be described.

Suitable frame plates in the frame of the machine (see Fig. 6) areslotted to receive a number of vertical plates I38. Carried on eachplate is a magnet which will be designated CS when the relay is used forcolumn shift purposes and X-I, X-2, X-4, etc. when the relay is to beused for multiplier selection purposes. These magnets CS or X whenenergized, serve to control the relays of the muiti-contacts. Preferablythe magnets CS or X are used as trip magnets only and the armatures ofthese magnets are not required to actually shift their related contacts.Furthermore provision is made for relieving the strain
